If you’re unaware of Instagram’s successful Android launch, it started with the app reaching 1 million downloads in under 24 hours. It then only took another five days for the company to add another four million downloads, surpassing the 5 million mark on its sixth day of availability.

Today it has doubled that tally, taking a little over two weeks to do so:

Android users had been waiting a long time for the photo-sharing app to launch on the platform, and even when the company launched its pre-registration process, Android smartphone owners rushed to be a part of it. When it opened pre-registration for its Android variant on March 24, it attracted 430,000 pre-registration signups in the following days.

Instagram currently has more than 47 million users (not all are active), with it certain to reach the 50 million milestone in the coming days.

With news of the acquisition hitting media outlets and news channels the world over, more and more users are becoming aware of the service and seeing friends and family interact and share photos using the app to Facebook and Twitter, helping it move into the mainstream.

Facebook may have paid a hefty price for the popular app, but given its increasing popularity and huge usage, it is looking to be a very smart buy by Zuckerberg and co.
